Scraped surface heat exchanger XTUBE BOXER®

liquid/liquidstainless steeldrive

A new Scraped Surface Heat Exchanger specially suitable for processing high viscosity fluids or for high fouling applications. Description The Xtube Boxer® heat exchangers are a new design of Scraped Surface heat exchanger which is being patented by XLG. The heat exchanger incorporates a tube bundle with heating or cooling fluid passing through the interior of the tubes (the Service fluid) with the fluid to be processed (the Product) passing over the external surfaces of the tube bundle. The heat exchangers are fitted with an electric motor and gearbox which drive the scraping elements. Movement of the rotor displaces the scraping elements along the length of the tube bundle, which results in the outer surfaces of the tubes being cleaned of any fouling deposit while the Product fluid is agitated and mixed. The movement maintains the outer tube surfaces clean and improves the rate of heat transfer into or out of the Product. Various types of scraping elements are available, chosen to enhance the rate of heat transfer with highly viscous fluids or to provide efficient cleaning of the outer tube surfaces for highly fouling fluids.
